Simple Filtration

Solid supported catalysts have been of considerable interest in organic synthesis for the last few years. Solid support provides an efficient heterogeneous catalytic system owing to facile recovery and extensive recycling by simple filtration because of possessing 3-R approach (Recoverable, Robust and Recyclable) and makes solid supported catalyst more appealing nowadays. In view of the high cost and shortage of furthermost used palladium catalyst, its recovery and recycling are vital issues for any large-scale application which are being overcome by using solid supported catalytic systems. Therefore, a variety of inorganic and organic solid-supported catalytic systems have been developed so far in order to address these challenges. This review attempts highlight a number of solid supported catalytic systems in the pro-active area of widely used C-C cross coupling reactions.

Increasing Demand

Transition-metal mediated C–H bond activation and functionalization is one of the most straightforward and powerful tools in modern organic synthetic chemistry. Oxidative C–H/C–H coupling reactions between two (hetero)arenes under heterogeneous catalysis may be a valuable means for the production of a plethora of bi(hetero)aryls, and one that adheres to the increasing demand for atom-economic and sustainable chemistry. We have therefore developed a reusable heterogeneous catalytic system, which is based on Pd cross-linked β-cyclodextrin, to perform an efficient microwave-assisted oxidative C–H/C–H cross coupling process between benzothiazoles and methyl thiophene in the presence of green solvents.
